To all whom it may concern:

Be it linowirthat l. Hitnnnn'r W. Aurex, a citizen o-the United States, and n resident ol' the city'ol' (hun ton, county of Stark, nud State of Ohio, have invented l0 No. 606,635, dated June 28, 1898` so as to simplifyY the construction thereof, render the salu(- nrorc compact, decrease the cost ol ininuilacturc. and secure other advantages hereinat'ier more fully appearing.

My .invention consists in the parts and iu the arrange- 15 ments and combinations of parts licreiimft er described and claimed.

ln the :accompanying drawing, which orins port of this specitication, and wherein like syinhols rt to like parts Wherever they occur7 Figure l is a longitudi- 2@ nal sectional view of my bearing applied to a motor shaft; Fig. il isn view of the outer end thereof with the dust cap removed; Fig. 3 is a sectional detail view ol' a portion of the bearing surface showing zi single roller in position; and, Fig. -l is a view similar to Fig. 3 showing a roller 0i modified forni.

Mounted upon the end of a motor shaft l is a conical sleeve which is pro vided :it its outer end with an annular rih or enlargement 3. The inner face or shoul der o the rib 3 is beveled or inclined, and preferably n cirn0 Cnmierential groove 4 is orined at the hase of the shoulder in order to provideclearance lor the grinding toolin the process oi' manufacture. The smaller' end el the conical sleeve isv also beveled or inclined.

Surrounding the conical sleeve 2 and bea 'ing thereon re series oi conical rollers 5.

Those rollers 5 have axiel ,)inrles or projections t3 vvhich rest in holes or peri tions provided therefor in a skeleton cage. This Cage comprises parallel rings 7 secured together by ineens o rorls. The coge serves to keep the rollers 'fl properly spaced and tendsio restore to proper position any roller that may have hec'oine' canted.

The smaller end ol each roller is provided with an annular rih or enlargement 9 .rhose inner shoulder is beveled correspond with "the bevel of the smaller L- end of the conical sleeve 2. The larger end of the roller is reduced in diameter to clear the rib 3 on the ermical sleeve, and the shoulder l0 thereby orinedis beveled to cori spend with the bevel of said rib 'The shoulders of the roller are so located that when one ot' them bears against the smaller end o the conical sleeve 2 the other shoulder l() or' the roller will bear against the shoulder' ol' the rib 3 ut the larger end of n said conical sleeve. Surrounding the rollers is the outer bearing piece ll, which, in the eoi'istruction illustrated in the drawing consists oi a cylindrical 55 shell or sleeve whose inner hice is iuadc conical.

Fig. l illustrates n. conrcnii-nt nienns ol applying my hearing to a shaft. for instance. to a. shalt of an electric motor. lu this case, the outer hearinf.,r pier-c or shell l l is mounted in the buh or motor hend provided thcrc- G0 for in the linnn '.rork l2. und its inner cud ahuts against a shoulder 13 insaid huh, The inner bearing piece or sleeve 2 is nrountcd on the niotor shalt', and is held against longitudinal movement hy means of a nut 14 which works on the threaded end oi' the shaft and is u1'- 65 ranged to constuuil; an aluitnient for said inner sleeve. lu practice this nut screwed horno. the adjustment oi' thc inner bearing holo@ etl'cctcd by menus oi' a greaterv or lcss nuiuhcr ol' shin-is 'sr Washers l5 interposed hetu'oen the nut :rnd the end nl snid inucr hearing piece, 'v70 Thil nut locked in position hy ini-ans of ordinary cottcr pins lt. The shalt is provided with a similar a1'w rangement at thc opposite end, The outer end of the h uh is screw threaded und provided with a threaded cap 17 designed to exclude dirt from the hearing but to 7 5 permit easy access thereto.

On account ol' the rollers being formed with a shoulder at each end to bear against corresponding portions of the inner bearing piece. the tendency ol' the rollers to cnntis to a large extent m'ercoinc. The inclination 0i 80 the shoulders has a tendency to reduce the friction at the ends of the rollers and to tight rollers that may have become cantcd. By reason ofthe shoulders at both ends of the roller being arranged to hear simultaneously against the c(rrrespondingl surfaces oll'the inner shell, 85 the disadvantage o'i cndwise friction isdto :t large extent overcome. .For the same reason, the wear at the ends. of the roller progresses evenly4 lly the construction hereinhelore described, n greater hearing surface is secured for a given length of roller 9G than has lheretofore heen practicable so that it is capa-- ble of use under conditions requiring great con'ipactncss of constriction. My hearing isl obviously/capable of, general use as a journal hearing or :t vehicle hearing or the like, and l do not Wish to he restri 'ted to its use in 95 connection with motor shafts.

The modification illustrated in Fig: fl consists merely in forming n groove 1S near the outer or smaller' end of the roller and in forming a corresponding rih 19 on the outer or smaller end ofthe conical shell 2 tio project into 100 said groove Both the groove and the ril) have beveled or inclined sides and preferably a slight grooye or deprt ssion 2i) is lurtned on the shoulder ai ihv hase of the rib. ln other respeets thv roller 5 shown in Fie. 4 la .similar to the roller ht-rvhthviorv dest'rihvdA What lvlalnt as my invention and desire in sentire by Lettera latent is:
